We present the clinical course of a premature newborn with a complicated neonatal respiratory course that was initially thought to be related to BPD, but it did not respond to the typical therapies for this condition. Due to the findings of periventricular nodular heterotopia, the diagnosis of a filamin A gene mutation was eventually made, which explained the respiratory pathology of this patient. When time of onset and clinical course do not correlate with typical BPD, one should consider alternative diagnoses in premature infants, including neonatal diffuse lung disease.
